i i Application leyd May 13, 1927. Serial Io. 191,009.

My invention relates to an automobile' i vsanding device, and in particular"y to a.` de? preference to the accompanying drawings" vice for distributing sand in the path of travel of the wheels of an automobile. The object of my invention is to provide a device of the above indicated character unlikely to get out of order., and is provided with a plurality of operating meanstherefor.V i y My invention will be best .understood by forming a part of this speciticatiomand in which,

- Figure 1 is .a horizontal sectional view of an automobile: incorpora-ting my invention.

Figure 2 is a horizontal sectional view of my invention disclosed in Figure 1.

Figure 3 is a cross-sectional view of the rear portion o1 that disclosed in Figure 1 and taken -on approximately Y the 'line '3-3 oi' Figure 1.

Figure4 is anfenlarged .seetionalview of the valve arrangement incorporated in my invention and,`Figure 5 is a plan view of that disclosed in Figure 4.

In the drawings and for the purpose of illustration I have shown the preferred embodiment of my invention in which 5 designates an automobile having wheels 6 and a rear seat 7. Under the rear seat 7 is positioned a sand box 8, of any suitable construction having an opening in the to and a cover 9 positioned within same. aid box is provided with a plurality of sand outlet extensions 10, which are connected to con-k duits 11 through which the sand 12 is adapted to kow when the rotary valves 13 and 14 are opened. The conduit 11 is provided with a flange 15 which is secured to the body of the automobile by means of suitable bolts 16 positioned through openings 17 in the flange 15. A reduced extension 18 on the upper end of the conduit 11 is adapted to fit overthe sand outlet extension 10, as shown in Figure 3.

The bottom end of conduit 11 is provided with a flange 19 to which a similar flange 2O on the distributing member 21 is adapted l as it V,passes through the same.

ated by means of arms 24vand25 respectively. vSaid arms .are connected together y y'by a "bar 26, and the bar 26 is provided withl which is relatively simple in construction,`

a pin`27 adapted to ride in theslot 28', in the crank 29, whichis rigidly'secured to an os-` cillatory shaft 30,1'by means of pin 31. They 36 whichengages a nut 37 on said rod, and

the vother end of said spring -36 engages a portion 38 of the car iframe. On 'the rod 33 is provided a nut 39, adapted to be engaged by a collar'40 and the collar 40 is provided with .pins41 which extend through slots 42 inthe hand operating lever 43, as shown in Figure 1. The hand lever 43 is'pivoted lon a bracket 44 and is provided with a hand grip 45 on the upper end for operating the same. A tubular member 46 is positioned between the frame portion 38 and the collar 42 for the purpose of limiting the rearward extension of said rod The forward end of rod 33 is provided with a slot 47 through which the pin 48 passes for the purpose of pivoting the latch 49 to said rod 33 and for allowing the rod 33 to reciprocate without interfering with the normal position of the latch 49. o

When it is desired to operate my sanding device by means of the foot brake pedal 50,

the latch 49 is vallowed to operatively engage thereby draws the cable vertically passing it over the pulleys 55 and lifting the forward end of the latch 49 and disengaging the same from the pin 51, on the foot pedal 50.

The opening through valve 13 is considerably larger than the opening through valve 14, and the purpose of this arrangement is to permit the sand pocket 56 to be suddenly filled with sand when the operating means is so positioned as to open the valve 13. The valve 14 is smaller and gradually supplies sand to the distributing member over a considerable period of time. The valves 13 and 'la are adapted to oscillate through an angle of approximately 90 degrees and When operated to their limit against the force of the spring 36, the valve lbecomes completely closed for preventing a continuous flow of sand from the sand box through the sand distributing member and this permits the operator to solidly hold his brake 'for an indeiinite period Without an excessive loss of'sand supply` By means of the hand lever 45 and the disengaging lever 49, it is possible to distribute sand in the path of travel ot the Wheels when driving up a steep, slippery hill Without the necessity of operating the brakes and by this arrangement it is obvious that sand may be distributedy in the path of travel oit the Wheels When going up or down hill and With or Without the use of brakes.

Having described my invention in its pre-s lieired form, it is obvious that variations the scope ot the appended claims.

I claim as my invention: l. In combination with an automobile; Wheels on said automobile and means for .distributing sand in the path of travel nt said Wheels; a sand box for supplying san-d to said distributing means; a conduit communicating with said sand boX and said kdistributing means, for permitting sand to pass to said distributing means; said conduit having valves therein for regulating the passage ot' sand therethrough; means for permitting the fiowof sand When the brake pedal is depressed and means for permitting the iow of sand independent or" the operation of said brake pedal. y

2. In combination vvith an automobile; Wheels on said automobile and means for distributing sand in the path of travel of said Wheels; a sand box for supplying sand to said distributing means; a conduit communicating With said sand box and said distributing means; a plurality of valves Within' said conduit; a sand pocket in said conduit between said valves; and manually oper- -ated means for controlling said valves; one of said valves adapted to admit a sudden flow of sand to said pocket and the other valve adapted to permit a gradual flow of sand from said pocket to ysaid distributing means and the first said valve being adapted to shut o the supply of sand Jfrom said box when said operating means reaches its limit of movement.

In testimony whereof I have signed my name to this specification. FREDERICK F; F. BEHRENS.
